Yes, the merged image contains the same image information the tiles have. You can easily check that by merge 2 tiles, import the merged image and the both tiles into your favorite image processing tool and perform an image substraction. Beware, the lossy image compression, like in jpg, can reduce the quality of the images and therefore the substraction is not equal to zero.
The JPEG format is based on a lossy image compression algorithm. The loss of information when using JPEG output in PointCab is insignificant. But, if you load/save the JPEG images more often, more and more information will be neglected.
Personally, I prefer PNG images (using lossless compression).
Beside the merged image, a txt file containing the image corner coordinates will be created. You can easily use this coordinates to adjust (scale, move) the image in your favorite CAD application.

should I use png instead of jpg? What is your recommendation?

Is it scalable?

1. When the tiles are merged, are the file sizes too large for AutoCad to manipulate as a traceable 24" x 36" image?
2. What problems arise using the merged images, vs. the standard tiles?
